Use of supercritical fluid extraction for sample preparation of sustained-release felodipine tablets.

Abstract

Supercritical fluid extraction (SFE) was shown to be an accurate and precise alternative to liquid extraction for sample preparation of sustained-release felodipine tablets (5 mg potency) while realizing an 80% reduction in solvent consumption. Extractions of felodipine spiked on an inert support were used to evaluate the solubility of felodipine in CO2 as… (More)
